PostgreSQL is a very powerful open source database management system. It's licensing is clear in that you can use if for whatever you like. That includes using it in a commercial product.

What we like about PostgreSQL:

  • No licensing issues.
  • Standards  based.
  • Highly scalable.
  • Fast and powerful. Can handle billions of records.
  • Publicly available support is good.

What we don't like aboiut PostgreSQL:

  • Is challenging to install, update, and maintain.
